  • Page 34 S E C T I O N T e c h n i c a l D e s c r i p t i o n As a result, the current through the chain [control thermistor - R202 - R01/9] is roughly proportional to the recirculating solution temperature, and thus, so is the voltage sample at R202 slider.

  • Page 35: Digital Display

    S E C T I O N T e c h n i c a l D e s c r i p t i o n Digital Display The temperature control thermistor is one of a pair, siamesed together in the heater housing. The other of these provides a user display of the recirculating solution temperature and, as we will see later, protection in case of failure by the first thermistor.

  • Page 39 S E C T I O N T e c h n i c a l D e s c r i p t i o n Pressing the Alarm Test button artificially lowers the set point by making U3.6 short out R606. Since the set point is lowered to below room temperature, this should set off the alarm whatever the actual fluid temperature.
